It features a storage capacity of 4K words by 9 bits, providing a total of 36 kilobits of data buffering capability. The device operates with a maximum access time of 35 nanoseconds, ensuring timely data throughput for high-speed digital systems. It utilizes standard synchronous logic interfaces for reliable clocked data transfer and includes control signals for read and write operations.

FIFOs Memory Feature Summary

• Synchronous FIFO architecture for controlled data buffering
• 4K x 9 bit memory organization
• Standard logic interface for system integration

FIFOs Memory Applications

• Data buffering in digital signal processing chains
• Interface bridging between asynchronous system components
• Temporary storage in high-speed communication protocols

FIFOs Memory Procurement Notes

Verify the manufacturer designation as Quality Semiconductor to ensure component authenticity. Confirm the suffix JR corresponds to the specific package and temperature range required for your design. Cross-reference the 35ns speed grade against system timing requirements before finalizing procurement orders.

FIFOs Memory Selection Notes

Select this component when a 4Kx9 synchronous FIFO buffer is required with a 35ns access time constraint. Ensure the system voltage levels match the device specifications. Consider the physical package type associated with the JR suffix during PCB layout planning to maintain signal integrity.

FIFOs Memory Part Context

This part belongs to the QS72241 series of synchronous FIFOs from Quality Semiconductor. The series offers various speed grades, including 15ns, 25ns, and 50ns variants, allowing designers to balance performance and power consumption. The 35ns variant provides a middle-ground performance option for applications not requiring the fastest available speeds.

FIFOs Memory Replacement Considerations

Compatible alternatives within the same series include the QS72241-25JR for faster operation or the QS72241-50JR for lower cost applications. Verify pin compatibility and electrical characteristics before substituting.
